The acquisition method of the present embodiment WLAN hot spot locating information is applied to mobile network's terminal with satellite positioning functions (as GPS positioning function, Big Dipper positioning function etc.), and as shown in Figure 1, described method comprises:
Step 110, opens the WLAN in this terminal and WLAN hot spot locating information reporting functions;
WLAN hot spot locating information reporting functions can realize in terminal applies.But in the present embodiment, be ready to make user report and therefrom benefit, using WLAN positioning function as the option in terminal configuration, after the option of WLAN positioning function is selected, automatically open WLAN hot spot locating information reporting functions.That is, WLAN hot spot locating information reporting functions and WLAN positioning function are associated, WLAN hot spot locating information will be reported to enjoy WLAN positioning function as user voluntary accordingly.The unlatching of reporting functions can give user and point out clearly.
Step 120, terminal detects the signal of WLAN hot spot;
The WLAN Function detection of terminal, after the signal of WLAN hot spot (also can be described as access point (AP:accesspoint)), without the need to connecting, can obtain WLAN hot spot and having the mark of uniqueness and the information of signal strength signal intensity.
Step 130, whether terminal judges WLAN hot spot meets the report condition of setting, as met, performs step 140, as do not met, continues to detect;
When new WLAN hot spot being detected, can namely trigger the above-mentioned judgement of this step.
Sometimes, the signal strength signal intensity of the WLAN hot spot that terminal detects is very high, the WLAN hot spot of such as middle setting in public places.But, these WLAN hot spot do not need much more very on offer and calculate its position, utilize the reporting information of the user connected with WLAN hot spot just enough.And for terminal, the WLAN hot spot detected every day is very many, but the WLAN hot spot really connected is also few.Therefore, the present embodiment judges whether WLAN hot spot meets the report condition of setting, is connecting successfully with WLAN hot spot, judges whether the WLAN hot spot connected meets the report condition of setting.For the WLAN hot spot do not connected, do not process.To avoid frequent judgement,
In this step, only exemplarily, the condition of described setting comprises one or more conditions following:
